An electronic device includes an audio capture device operable to receive audio input, a fingerprint sensor operable to receive fingerprint data, and one or more processors, operable with the audio capture device and the fingerprint sensor. The fingerprint sensor can authenticate a person as an authorized user of an electronic device while device commands are being received in the form of audio input to allow for secure voice interactions without requiring a trigger phrase. The fingerprint sensor can be used in combination with the receipt of voice input to perform two-factor authentication. The fingerprint sensor and audio capture device can be used in combination to enroll, or update enrollment, of a user interacting with a voice assistant as well.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An electronic device, comprising: an audio capture device; a fingerprint sensor receiving fingerprint data and, upon identifying the fingerprint data as belonging to an authorized user of the electronic device, causing the audio capture device to capture audio input; a voice interface engine operable with the audio capture device, the voice interface engine, upon identifying a device command in the audio input, attempting identification of a source of the audio input from the audio input; and one or more processors operable with the voice interface engine, the one or more processors executing a control operation in response to the device command identified in the audio input only when the voice interface engine identifies the source of the audio input as the authorized user of the electronic device.
2. The electronic device of claim 1 , further comprising a user interface, the one or more processors requiring capture of at least one additional authentication input by the user interface when the fingerprint sensor fails to identify the fingerprint data as belonging to the authorized user of the electronic device.
3. The electronic device of claim 2 , the one or more processors executing the control operation only when the at least one additional authentication input matches a predefined criterion.
4. The electronic device of claim 1 , further comprising a user interface, the one or more processors requiring capture of at least one additional authentication input by the user interface when the fingerprint sensor identifies the fingerprint data as belonging to the authorized user of the electronic device and the voice interface engine fails to identify the source of the audio input as the authorized user of the electronic device.
5. The electronic device of claim 4 , the one or more processors executing the control operation only when the at least one additional authentication input matches a predefined criterion.
